Product Description
180μm Black CPE Base Film
Ultra-heavy-duty industrial-grade black cast polyethylene base film engineered for exceptional tensile strength, tear resistance, and puncture-proof performance. Features smooth surface for lamination compatibility with optional anti-static treatment.
Production Process
Manufactured using advanced ultra-precision cast extrusion technology with high-purity LDPE resin homogenously blended with light-fast black masterbatch. Process includes temperature-calibrated extrusion (175-195℃), high-precision flat die casting onto mirror-polished cooling rollers, and strict thickness calibration to ensure stable 180μm gauge with uniform opaque black coloration and smooth surface finish.
Key Features
- ±4% thickness tolerance ensuring uniform density and mechanical stability
- Superior light-blocking and UV-shielding capabilities with excellent color fastness
- Exceptional tensile strength, high tear resistance, and robust puncture-proof performance
- Reliable flexibility and low-temperature toughness (-10℃ to 65℃)
- Ultra-smooth surface for seamless lamination and coating compatibility
- Optional anti-static treatment for specialized industrial requirements
Product Advantages
- 180μm ultra-heavy-gauge structure outperforms thinner alternatives in durability and impact resistance
- Uniform opaque black color enables instant visual identification in production lines
- Exceptional batch-to-batch consistency minimizes conversion waste and improves efficiency
- Non-toxic, odorless, and compliant with global industrial standards
- Cost-effective solution supporting steady bulk supply for high-demand applications
Application Environment
Optimized for ultra-heavy-duty industrial scenarios including heavy-duty light-blocking packaging, robust surface protection for large machinery, automotive component shielding, and high-demand privacy protection films. Maintains structural stability during high-speed slitting, lamination, and coating processes in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃).
